The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and short-term ratings, due to the difference in motor specifications, despite the fact that two motors have the same output power.Motor Sizing Calculations - Alaa Khamis,The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and short-term ratings, due to the difference in motor specifications, despite the fact that two motors have the same output power.Electric Motors and Drives - UF MAE,Electric Motors and Drives . To calculate the peak power and torque produced by an electric motor, you will need to know the following: • Motor supply voltage : V s [V] • Peak motor current: I s [amps] • Motor velocity: N [rpm] The power produced by the motor can be calculated as: P [watts] = V s [volts] × I
In our example input electrical power of the motor is 0.22 A x 6 V = 1.32 W, output mechanical power is 1000 rpm x 2 x 3.14 x 0.00126 N•m /60 = 0.132 W. Motor torque changes with the speed. At no load you have maximum speed and zero torque.Determining Electric Motor Load and Efficiency,Figure 3 Relationships Between Power, Current, Power Factor and Motor Load Example: Input Power Calculation An existing motor is identified as a 40-hp, 1800 rpm unit with an open drip-proof enclosure. The motor is 12-years old and has not been rewound. The electrician makes the following measurements: Measured Values: V ab = 467V I a = 36 amps,Electric Motor Calculator - Engineering ToolBox,RLA - "Running Load Amps" - current drawn during normal operation of electric motor. FLA - "Full Load Amps" - amount of current drawn when full-load torque and horsepower is reached for the motor.FLA is usually determined in laboratory tests.Note! - in the calculator above FLA is RLA + 25%. 1 hp = 0.745 kW; Related Mobile Apps from The Engineering ToolBox,
greater for reversible motors than for non-reversible motors and therefore the minimum starting torque is smaller for these mo-tors.
